Abstract

The public health burden of type 2 diabetes mellitus has been dramatically increasing world-wide. The chronic complications of type 2 diabetes play an important role in decreasing life expectancy and adversely affecting quality of life. Diabetic nephropathy, which is originally microvascular in nature, is widely considered an important complication of diabetes. In prospective clinical investigations, increased urinary albumin excretion proved to be associated not only with subsequent renal outcomes but also with cardiovascular morbidity/ mortality independently of other risk factors. Therefore, microalbuminuria as an early sign of increased urinary albumin excretion should be considered important for both treatment and even for prevention. Preventing microalbuminuria might diminish progression to overt nephropathy and, hopefully, might limit cardiovascular events. Regarding primary prevention of diabetic nephropathy, therapeutic intervention should optimally be initiated at the stage of normoalbuminuria. Although additional factors such as smoking cessation, reduction of protein intake, and treatment of lipid abnormalities are important, providing optimal diabetic control as well as targeting optimal blood pressure are the key elements of a prevention strategy in diabetic patients. Recently, the Bergamo Nephrologic Diabetes Complications Trial (BENEDICT) documented that a significant decrease of the development of persistent microalbuminuria could be achieved by using an ACE-inhibitor, trandolapril alone or in combination with verapamil SR, a non-dihydropyridine calcium-channel blocker in hypertensive type 2 diabetic patients with normoalbuminuria. The results of this primary-prevention strategy should be corroborated by further investigations to determine whether these beneficial changes could later result in improvement of renal clinical outcomes, macrovascular complications, or both.
